Landranger maps are the successors to the old one-inch maps. The scale is now 1:50 000.
These maps show much of the topographical information found on the Explorers, though not field boundaries, and also include rights of way, some permitted routes, major long distance paths, cycle routes and selected tourist attractions. Landranger maps are a multi-purpose map for planning a great day out in the countryside and for easy cycle touring. £6.99 each
The full range of Ordnance Survey maps is available online from the Ordnance Survey online map shop. However, of necessity, the post and packing on their service will be about £2.50 for one map.
